Lost sleeping bag at the Carotel

I've just realised I left my prize sleeping bag at the Carotel in Canberra on Sunday morning.
I used it as a pillow on the bottom bed in the far corner.
If anyone found it, please let me know.
It is a Fairydown in a blue Fairydown stuff sack.
I will be forever indebted to anyone who can help me get this back.
I can't sleep as I've just realised.
